ASEAN Perspective
Ambience Healthcare in Southeast Asia
Ambience Healthcare is currently a US-focused product with no confirmed deployments, regional data-residency infrastructure, or local sales presence in ASEAN or broader APAC as of mid-2026. The platform's CDI and coding modules are calibrated to US-specific frameworks (ICD-10-CM, CPT, CMS compliance), which limits direct applicability to healthcare systems operating under ICD-10-AM (Australia, Singapore, Malaysia) or ICD-10-BN without significant customisation. ASEAN health systems exploring ambient AI documentation should monitor Ambience for future international expansion while evaluating locally available alternatives in the interim.
Ambience is one of the more substantial ambient-AI vendors: enterprise rollouts at Cleveland Clinic and Houston Methodist, a peer-reviewed account of onboarding 4,000+ Cleveland Clinic clinicians in four months, the 2026 KLAS/CHIME Trailblazer Award, and coding support that reasons over the whole chart rather than only the conversation. Treat its performance figures with care, though: the 27% coding result is the company's own benchmark and the $13,000-per-clinician figure is one customer's KLAS case study.
It is enterprise-only, unpriced in public and contracted on outcome targets, so it suits large US systems that can negotiate those targets. Small practices, and anyone outside US billing codes and EHRs, should look elsewhere.
What we found
Ambience Healthcare is a San Francisco company, started in 2020 by Mike Ng and Nikhil Buduma, that sells an AI platform to large US health systems. It began as an ambient scribe that turns a clinician-patient conversation into a note, and now covers chart summaries before a visit, notes, orders and patient instructions during it, and ICD-10, E/M and HCC coding support afterwards. It runs inside Epic, Oracle Cerner and athenahealth across more than 200 specialties, the company says. Since February 2026 much of it is chart-aware, reasoning over labs, imaging and prior notes as well as the conversation, and a nursing suite followed in June.
The headline numbers mostly come from Ambience or its customers. Its claim that a coding model beat 18 board-certified physicians by 27% describes a relative reduction in errors on the company's own test set, announced in May 2025; earlier versions of this page called it independent testing. The $13,000 per clinician a year in extra coding revenue is one customer, St. Luke's Health System, in a KLAS case study, and Houston Methodist's 40% cut in documentation time comes from an Ambience release announcing that system's enterprise rollout. Two outside sources stand up better: a peer-reviewed npj Health Systems paper on how Cleveland Clinic onboarded more than 4,000 clinicians in four months, and the 2026 KLAS/CHIME Trailblazer Award.
A $243 million Series C in July 2025, co-led by Oak HC/FT and Andreessen Horowitz, took total funding to $345 million and, according to Fierce Healthcare, the valuation to $1.25 billion. No later round has been announced.
Prices are not published. In August 2026 Ambience introduced what it calls The Ambience Standard: forward-deployed clinical and engineering teams inside each customer, and contracts that put its fees at risk against the health system's own outcome targets rather than charging per seat. That suits large systems and rules out small practices, and everything is built around US billing codes and US EHRs, with no stated presence outside North America.
